Topics in Equilibrium
Every topic of Equilibrium, ordered by how many published questions sit behind it. A topic with none is listed rather than hidden — it is part of the chapter either way.
- Law of chemical equilibrium; Kp and Kc
- Buffer solutions and their pH
- Solubility product and the common ion effect
- Factors affecting equilibrium; Le Chatelier's principle
- Hydrolysis of salts
- Equilibrium in physical processes
- Acids, bases and salts; Arrhenius, Bronsted-Lowry and Lewis concepts
- Ionisation of acids and bases; Ostwald's dilution law
- Ionic product of water and the pH scale
Equilibrium weightage in NEET-UG 2026 and JEE Main 2026
These shares are measured across many years of past papers, so they describe the long run rather than predicting any single paper.
| Paper | Share of Chemistry | Typical questions | Typical marks |
|---|---|---|---|
| NEET-UG 2026 chapter-wise weightage | 5.4% | 2.4 | 9.8 |
| JEE Main 2026 chapter-wise weightage | 5.4% | 1.4 | 5.4 |
Previous year questions from Equilibrium
Past-paper questions are the most trustworthy material in the bank, and assembly reaches for them first when it builds a Equilibrium test. They are not listed separately here, because a question's value is that you meet it under a clock rather than that you read it in a list.
A Equilibrium test draws from all 270 published questions in this chapter, past papers first. Sit one now and see the per-topic breakdown.
